The MagnaFlow Rock Crawler Series Cat-Back Performance Exhaust System 15239 delivers superior off-road and rock-crawling performance to your 2007–2011 Jeep Wrangler equipped with a 3.8L engine. Designed specifically for demanding terrain, this system features a weight-optimized, dyno-tested, corrosion-resistant stainless steel construction engineered to closely hug the undercarriage for improved ground clearance.
This exhaust system produces MagnaFlow’s powerful, resonant signature exhaust tone with aggressive exterior sound levels and a moderate interior tone, offering the perfect balance of performance sound and control on and off the trail.
Exhaust kit 15239 features an emissions-legal cat-back configuration, replacing the factory exhaust components from the catalytic converter to the rear of the vehicle. The system utilizes 2.5-inch mandrel-bent main piping, flowing through one straight-through muffler, before terminating in a single straight driver-side rear exit.
The tipless turndown-style exit improves departure angles, giving you more flexibility when navigating rocky terrain, steep inclines, and other off-road obstacles. Extensive 3D scanning during development ensures a precise direct-fit design, making this system easy to install at home.
Manufactured using advanced CNC robotic precision techniques, exhaust system 15239 is backed by MagnaFlow’s limited lifetime warranty.
